VALVE.

Application led November To all whom imag concern:

Be it known that i, JOHN A. CARS-0N, al

citizen of the United States, residing at Huntington, in the countyl of Suffolk' and State of New York, have invented new and uesful Improvements in Valves, of which the following is a specification.

This invention relates to valves and is of a type, intended inv one instance, to be applied to the transmission cassof an automobile for ascertaining the level of oil within such case; it being of prime importance that the exact amount of oil within ,thev case` be known for the roper maintenance and upkeep of the englne. This' use however, is'only one ofnumerous uses, equall as important, to which the valve herein isclosed may be put, therefore, it is to beunderstood that no limitation is necessarily made to the present use..

With vthe above andA other objects in view, the invention resides in the simplification and in the reduction in cost of manufacture of a valve of the character mentioned and which is of such construction` and whose parts are so arranged that it may lbe'easily and conveniently opened* for its intended pupose and which automatically closes itsel In the drawing :-l y Figure 1 is a view il-lustratingthe application of the valve to the crank case andthe disposition of the valve plug actuating memer. v

Fi 2 isa central sectional view takeny on the line 2-2 of Fig. 1. y f 'l Fig. 3 is a transverse sectional view taken on the line 3-3 oit-Fig. 2.l

At .the present time, 'applied to .the transmissionjcase or crank case of `an automobile :.engine, there arepet cocks, with whichthe level of the oil'y within suchcases arev ytested 1 orascert'aied. Such 'cocks-.are found. to

.l to actuate them. -B the use''ofthepartici'i-v be wholly unsuitable for this purpose, since considerable v[inconvenience and "ti-onblefattends their being opened and closeda-requiring va/ person :to get beneath the, engine lar valve herein disc osed such inconvenience and trouble may be obviated-slnce'the 'valve y is of such construction that it maybe opened from a point at one side of the automobile bya simple outward pullthe valve automatically closing itself vupon vthe, cessation ofthepull. ,v

Referring now to the'draw1ng,it will be f Specification of Letters Patent.

1 Patented June 14, 19271. 15, 1 919. semi No. 338,247.

seen'th'atl the v,valve comprises a body 10 which is provided with an integral screw threaded extension 11. In the extension 11, extending centrally therethrou h is a .passage 12 which communicates wit disposed opening or bore 13 in thebody 10.

a centrally l This bore' 13v is conformed to receive a tai ered 'or cone-'shapeplug 14 which normally ies disposed against seat 15 formed by the wall ofthe bore 13.y

In order that the plug 14 may be lieldknormally against seat 15, the plug 14 is provided vwith a reduced threaded extension 16 at one end thereof and a spring 17 surrounds the extension 16 and is interposed between a nut 18.at the end of the'extension 16 vand a y washer 19 which encircles the extension. 16 contiguous the body 10.

In order that the plug 14 may be moved to'an opened position conveniently, from a point at one side of the automobile there is provided a pull member 20 having one end thereof attached to an apertured extension 21 on the plug 14, the other end of the member 20 being disposed in a guide member se- Y cured to the underside of the running board 23, clearly shown in Fig. 1 of the drawing.

The otherend of the pull member 20 is provided with a linger ring 24. The'threaded end ofthe extension 1l is received in a threadedaperture in the crank case 25.

From the 'foregoing it will be manifest that 'there is provided a valve which is Vof simple construction. and which isv particularly suitable to permit its being opened froma remote point, conveniently and'effectually; that by pulling outwardly onthe 'member'20v the plug 14 will be moved toa position to` permit the oil to flow through the passage 12 into an established passage between the face of the plug l4`and the. seat 15 ofthe body'lO; that upon releas ingthe pull on mem-ber 20, the plug will `au,tomateicallymove back toa closed position; that,byjfreason-of the particular construction of the valve, it cannot in any way become impaired from. dustfdirt, or other foi'- l out and` carries; with Vit anythingfabout the vopen end ofthe -,bore `and vno foreign matter eign matter, as is the case withfpet-cocks` ean enter the'bore while the lilm of. oil exists between the. Vplugfand the bore. What is elaimed as new is 41. A' valve structure as eliaraeterized eoin-` v prisiiig a body having a tapered bore therein and a sei-ew threaded stein extending from saidibodyv and having a passage opening to said bore, a tapered plug arranged for reeiproeatory.movement ii'isaid bore and extendingfroiiiend to yend thereof, the plugbeing movable to permit the tiow'of a fluid through said passage and Vsaid bore. means at one side of the bodvfor` holding the. plug in said bore and permitting the movement of the plug. and means at'thejopposite side of said body for moving the plug.

2. A valve strueture as ehai'aeterized eoniprising a body having a straight tapered bore therein and a screw threaded stem extending.froiiisaid body'and having a pas sage therein opening to said bore, a tapered plug arranged for reciproeatory movement in said bore vandextending from endto end thereof. the pluor being movable to'permit the flow of aV nid through said pas sage and said bore. yieldable means at one side of the body for holding the plug iii said bore to preventtlie ilowot' a lluid through the passage and the bore and permitting the movement ot' the plug to permit.

the flo'w of u fluid as stated, and means l'oi' .moving the plug from a reiiiote point.

3. In` a valve structure foi' use in eoiiiieetion with the transmission ease of an engine 1 for determining a -tixed levelrof oil in the ease. a hollow stenrprovided with means for eonneetion with the said ease at a point in line with the level ol' the oil to be deteriii-ined, n body on wliieh the stein is formed, a tapered bore opened through one end of the bod a ta )ered plug eoacting with the bore an( movalile therein to )ei-mit a flow of fluid through the stem and the bore, and means for normally positioning the plug to sliutol' eoniniuneatioii between the hollow stem and the said bore and allowing the reciproeation of said plug. .A

In testimony whereof I have aflixed my signature.
